Validated by Selleck labs. Should you need adjustments to this formulation, contact our sales team for custom testing.

 2.500mg/ml (6.18mM) Taking the 1 mL working solution as an example, add 50 μL of 50 mg/ml clarified DMSO stock solution to 400 μL of PEG300, mix evenly to clarify it; add 50 μL of Tween80 to the above system, mix evenly to make it clear; then continue to add 500 μL of ddH2O to adjust the volume to 1 mL. The mixed solution should be used immediately for optimal results. 
* <1 mg/ml means slightly soluble or insoluble.
* Please note that Selleck tests the solubility of all compounds in-house, and the actual solubility may differ slightly from published values. This is normal and is due to slight batch-to-batch variations.
* Room temperature shipping (Stability testing shows this product can be shipped without any cooling measures.)

Biological Activity

Description MCC950 (CP-456773, CRID3) is a potent and selective inhibitor of NLRP3 (NOD-like receptor (NLR) family, pyrin domain-containing protein 3) with IC50 of 7.5 nM and 8.1 nM in BMDMs and HMDMs, respectively.
Targets
NLRP3 [1]
(BMDM-based assay)		 NLRP3 [1]
(HMDM-based assay)
7.5 nM 8.1 nM
In vitro

MCC950 specifically inhibits NLPR3 inflammasome activation.[1]
In vivo

Inhibition of NLRP3 with MCC950 ameliorates proteinuria, renal histological lesions and podocyte foot process effacement in lupus-prone mice.[1]

Protocol (from reference)

Cell Assay:

[1]
  • Cell lines

    NZM2328 podocyte cell line

  • Concentrations

    1 µM

  • Incubation Time

    24 h

  • Method

    The NZM2328 podocyte cell line was stimulated with a control serum or a serum from diseased NZM2328 mice or serum from diseased NZM2328 mice depleted of IgG, with or without MCC950 or Mito TEMPO for 24 hours. After this incubation, cells were subjected to flow cytometry and Western blot analyses for NLRP3 inflammasome activation, mitochondrial membrane potential and production of reactive oxygen species (ROS) analysis.

Animal Study:

[1]
  • Animal Models

    female NZM2328, a new NZM strain produced by extended backcrosses of NZB/WF1 to NZW mice

  • Dosages

    10mg/kg

  • Administration
